The only unidirectional radial constraint of particular roll 18 being moved radially outward.
The example of the engaging mechanism is realized in column 52 and bonding part 54, and the gripping edge 50 of sliding block 40 realizes the phase
To the example of engaging mechanism.
Transmission device 1 during normal operation, in initial or rest configuration, under low engine speeds, that is, be less than
When the predefined thresholds of engine speed, transmission device is in low-grade location state, wherein the first half pulleys 8 and the second half pulleys 10
It is spaced apart and vee-belt has the winding diameter (Fig. 1) reduced.
Due to the centrifugal force of reduction, basic roller and particular roll 18 are in the radial position retracted, that is, close rotation axis X,
And it is consequently adapted to be engaged by sliding block 40.
In this configuration, regulating device is disabled, after control-rod 20 is in rear portion axial position, key 32a, 32b are in
Portion's radial position, in this position, they engage the actuating pin 22 for occupying recess portion 24, and sliding block 40 is in axial position,
In the position, it does not hinder the outward radial of key 32a, 32b to translate.
If since the configuration, engine speed increases, then the first half pulleys 8 make in this way close to the second half pulleys 10
It axle sleeve 9 must be moved escapes freely out sliding block 40 under the action of abutment element 30 and resetting spring 32 and be moved to rear positions,
Middle mobile axle sleeve cannot engage the particular roll 18 (Fig. 2) for being moved to position (i.e. far from rotation axis X) radially at the front.
Therefore, the high tap position for being transformed into transmission device is very unexpected, because all basic roller and particular roll 18 are all
Participate in gear shift.Therefore the setting of transmission device is touring.
Since initial configuration as described above, in order to enable gear shift regulating device, control foot 26 is activated, so that
Actuation spring 28 overcomes the opposite action of resetting spring 32 and actuating lever 20 is pushed into forward axial position (Fig. 3).
Since the sliding block 40 pushed by mobile axle sleeve 9 is in the front extreme position exited that will not prevent key 32a, 32b
In, so key 32a, 32b are moved to position radially at the front, come out from recess portion 24 and protruded outward from drive shaft 2.
Particular roll 18 is in rear portion radial position and is engaged by sliding block 40.In other words, the clamping of the flange 48 of sliding block 40
Edge 50 engages the bonding part 54 of the column 52 of particular roll 18.
If since this configuration (regulating device is activated and is engaged), regulating device, which is deactivated, (eliminates control foot
The effect of 26 control-rod 20), then regulating device returns to rest configuration (Fig. 1).
If since the low-grade location state of transmission device, wherein regulating device is activated and by engagement (Fig. 3), engine
Rotating speed increases, and basic roller operates on container 14 and transmission device is moved to high tap position state (Fig. 4), but particular roll 18 by
In being not involved in the gear shift by sliding block 40 is maintained at rear positions.
Therefore, compared with the case where all rollers participate in gear shift, the transition to high tap position is slow.The setting of transmission device
Therefore more motility.
In the configuration, although mobile axle sleeve 9 no longer pushes the sliding block 40 to front extreme position, due to key
32a, 32b, sliding block 40 are in forward position.
If regulating device is deactivated in the configuration, actually keep being engaged because sliding block 40 by key 32a,
32b maintains forward position, and the key 32a, 32b are maintained at position radially at the front, are maintained at this is because sliding block 40 limits them
Such position (protrusions 36 of actually engagement keys 32a, 32b of keyed end 44 of sliding block 40).After actuating lever 20 is moved to instead
Portion position.
Only when reducing engine speed, sliding block 40 is back into front extreme position by mobile 9 ability of axle sleeve, to release key
32a, 32b, the key 32a, 32b return to the rear positions in the recess portion 24 of actuating pin 22.
Therefore regulating device is no longer engaged；Increase engine speed again, transmission device returns to height in touring setting
Range state (Fig. 2).
If under the high tap position state of transmission device, wherein regulating device is deactivated (Fig. 2), then regulating device is opened
With the regulating device is to enable but do not engaged, and particular roll 18 keeps being released (figure from sliding block in the sense
5)。
In fact, by actuation control foot 26, actuation spring 28 pushes actuating lever 20 simultaneously to preload, but sliding block 40 to
Under the action of connecing element 30 and abutting spring 32, it is not subjected to the effect of mobile axle sleeve 9, is located at and is maintained at rearmost position,
In the rearmost position, it is axially across key 32a, 32b and key 32a, 32b is prevented to be moved to front from rear positions
It sets.
Therefore actuating pin 22 does not suffer from any translation.
Only when engine revolution is reduced, mobile 9 ability of axle sleeve pushes sliding block 40 to front extreme position, to release key
32a, 32b, key 32a, 32b come out from recess portion 24 and allow to move into front under the action of actuation spring 28 of the pin 22 in preloading
Position.
It is achieved in the low-grade location state of transmission device, wherein regulating device is activated and engages (Fig. 3).
Originally, the transmission device with gear shift regulating device makes under any state of transmission device (that is, low-grade
Position or high tap position) enable regulating device be possibly realized, this is because regulating device only just effectively engages under low-grade location state
Particular roll.
At the same time it is advantageous that deactivating for regulating device can carry out in any condition, this is because particular roll is effective
Release is only realized under low-grade location state, avoids impacting caused by the unexpected release during gear shift.
